List of all XCode project parameters or build settings. Where to find?

Hello all!

Trying to find list of all XCode project parameters or build settings within description. Is there any documentation? Need something that will help me to understand list of project properties when running command in project folder:

$ xcodebuild -showBuildSettings

Command line invocation:
    /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -showBuildSettings

User defaults from command line:
    IDEPackageSupportUseBuiltinSCM = YES

Build settings for action build and target test:
    ACTION = build
    AD_HOC_CODE_SIGNING_ALLOWED = NO
    AGGREGATE_TRACKED_DOMAINS = YES
    ALLOW_BUILD_REQUEST_OVERRIDES = NO
    ALLOW_TARGET_PLATFORM_SPECIALIZATION = NO
    ALTERNATE_GROUP = staff
    ALTERNATE_MODE = u+w,go-w,a+rX
    ALTERNATE_OWNER = alexandr
    ALTERNATIVE_DISTRIBUTION_WEB = NO
    ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = NO
    ALWAYS_SEARCH_USER_PATHS = NO
    ALWAYS_USE_SEPARATE_HEADERMAPS = NO

    and may other parameters

Need to know meaning of this kind of parameters.
